Professional Silver Dollar Authentication: How to Initially Distinguish Authentic from Counterfeit Old Silver Dollars?
Many collectors, when searching for "Hong Kong high-price ancient coin buying" or "high-price old silver dollar buyback" services, are most concerned about the authenticity and actual value of their collections. For valuable historical coins such as the Sun Yat-sen silver dollar from the 18th year of the Republic of China, Hong Kong Gold & Silver Exchange's experienced appraisal team has compiled the following basic "old silver dollar authentication" tips for you.
| Appraisal Dimension | Characteristics of Authentic Old Silver Dollars | Characteristics of Common Replicas / Counterfeits |
|---|---|---|
| Weight and Size | Standard weight typically ranges from 26.6g to 26.8g, with strict dimensions conforming to the mint standards of the time. | Weight is either too light or too heavy (often plated with silver over copper, lead, or alloy), with noticeable discrepancies in thickness and diameter compared to the standard. |
| Sound Identification | Tapping the edge produces a clear, prolonged, and soft sound, with the unique "reverberation" of a silver coin. | The sound is dull and short (high lead content), or excessively sharp and piercing (high copper or steel content). |
| Patina and Surface | Years of oxidation result in a natural, rich, and strongly adhered "patina" on the surface, with a subtle luster (commonly known as a "moist" feel). | The patina is superficial, with an unnatural and harsh color (often chemically aged or fire-treated), lacking the sense of accumulated age. |
| Edge Milling and Lettering | Edge milling is produced by large machinery, with consistent depth, neatness, and strength; lettering and portrait engraving are three-dimensional and clear, with vivid hair details. | Edge milling is rough and inconsistent in depth; the portrait face is expressionless, and the lettering edges are blurry or have small sand holes left by casting. |
